Warning assembly for reminding people of using times counted of edible oil in a deep fryer

ABSTRACT

Disclosed is a warning assembly for reminding people of using times counted of edible oil in a deep fryer, in which a thermal switch is electrically connected to a display and a buzzer. The thermal switch will sense the temperature change of an inner pot and take a reciprocal travel of the change thereof as a cycle, and it will actuate the buzzer to buzz for reminding a user of replacing the edible oil inside the deep fryer when the accumulated times of cycle reaches a predetermined number.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a warning device, and particularly to awarning assembly for reminding people of using times counted of edibleoil in a deep fryer, in which a thermal-control switch is electricallyconnected with a display device and a buzzer for recording and buzzing.

2. The Prior Arts

A conventional deep fryer is usually comprised of an inner pot as wellas a housing. The inner pot is placed inside the housing. A controlswitch is attached externally to the housing. To use the deep fryer,edible oil is first poured into the inner pot, and the control switch isapplied to ignite and the edible oil is heated to a proper temperature.Food is then put into the inner pot and fried until it is ready forservice. The food is then dredged out and the control switch is closeddown to complete the frying operation.

Since the conventional deep fryer is usually not provided with a warningdevice for reminding a user of replacing the edible oil after it hasbeen used as many times as predetermined, the edible oil is occasionallyoverused to create unexpected poisonous substances, harmful to people'shealth.

SUMMARY OF THE INVENTION

The primary object of the present invention is to provide a warningassembly for reminding people of using times counted of edible oil in adeep fryer by adding a thermal switch to an inner pot of the deep fryerfor recording temperature-change cycles, and actuating buzzing when theaccumulated times of cycle reaches a predetermined number.

In order to realize above object, a thermal switch is electricallyconnected to a display and a buzzer. The thermal switch will sense thetemperature change of the inner pot and take a reciprocal travel of thechange thereof as a cycle, and it will actuate the buzzer to buzz forreminding a user of replacing the edible oil inside the deep fryer whenthe accumulated times of cycle reaches a predetermined number.

The merits of the present invention is that since the thermal switchthat is capable of sensing temperature in the range from the roomtemperature to 110±50° C. for example, is disposed somewhere outside theinner pot of the deep fryer, on a bottom or lateral surface, forreminding a user of replacing the edible oil in the deep fryer when apredetermined number of times of use is reached, 15 times for instance.Thus, the quality of the edible oil can be ensured to thereby avoiddoing any harm to people's health.

For more detailed information regarding advantages or features of thepresent invention, at least one example of preferred embodiment will bedescribed below with reference to the annexed drawings.

BRIEF DESCRIPTION OF THE DRAWINGS

The related drawings in connection with the detailed description of thepresent invention to be made later are described briefly as follows, inwhich:

FIG. 1 is an exploded view showing inside structure of the presentinvention;

FIG. 2 is an assembled sectional view of the inside structure of thepresent invention; and

FIG. 3 shows a side elevational view of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

FIGS. 1-3 show an exploded view, an assembled sectional view and sideelevational view of inside structure of the present invention,respectively.

A warning assembly for reminding people of using times counted of edibleoil in a deep fryer is comprised of an inner pot 1, a thermal switch 2,a heating pipe 3, a heat-insulating pan 4, and a housing 5.

As illustrated in FIGS. 1 and 2, the inner pot 1, with the exception ofa foot portion 11 formed on the bottom surface thereof, coincidessubstantially with the housing 5 in shape. The thermal switch 2, whichfunctions to record temperature change, from room temperature to 110±50°C., for example, is disposed at a central position of the bottom surfaceof the inner pot 1. The heating pipe 3 is attached and extendedperipherally on the bottom surface of the inner pot 1. Theheat-insulating pan 4, which resembles the inner pot 1 in shape and isarranged to mate with the thermal switch 2 and the heating pipe 3, has athrough hole 41 in each corner for the foot portion 11 to get insertedtherein. The heat-insulating pan 4 also has two ends thereof checked attwo sides of the bottom surface of the inner pot 1 to combine with thelatter for heat insulation. Referring to FIG. 3, a deep fryer withwarning assembly of the present invention is completed by putting theinner pot 1, thermal switch 2, heating pipe 3, and heat-insulating pan 4together, then placing the unitary body in the housing 5.

Referring to FIG. 3 again and also FIGS. 1 and 2, a user is supposed tooperate a display device 51 on the housing 5. The display device 51 isdivided into two sections, in which one section is provided with a“HEAT” light 510 and a “POWER” light 511 to show the working conditionsand ON/OFF operation of the power supply; and the other section isprovided with a display 512 on an upper portion and a “TIMES” or a“TIME” indicator 513, 514 located aside.

After power is supplied to the deep fryer, a user is requested todepress first a Start/Stop key 517 under the display 512 to lighten the“HEAT” light 510, then a Mode switching key 515 to selectively lightenthe “TIME” indicator 514 or the “TIMES” indicator 513 to show theoperation mode of the deep fryer.

In the case of time setting, the user is now supposed to depress a “SET”button 516 to start operation of the display 512, and depress a “RESET”button 518 for resetting the system.

After the deep fryer starts to work, the thermal switch 2 will sense thetemperature change from the room temperature to 110±50° C. as one cycleand show it on the display 51, and at the moment when the accumulatedtimes of cycle reaches a predetermined number, it will notify a buzzer(not shown) to buzz to remind the user of replacing the edible oilinside the deep fryer to thus avoid doing any harm to people's health.

In the above described, at least one preferred embodiment has beendescribed in detail with reference to the drawings annexed, and it isapparent that numerous changes or modifications may be made withoutdeparting from the true spirit and scope thereof, as set forth in theclaims below.

1. A warning assembly for reminding people of using times counted ofedible oil in a deep fryer, in which a thermal switch which iselectrically connected to a display and a buzzer is provided to an innerpot.
 2. The warning assembly as claimed in claim 1, wherein the thermalswitch senses and takes a reciprocal travel of temperature change of theinner pot as a cycle, and show the accumulated times of cycle on thedisplay and actuate the buzzer to buzz when a predetermined times ofcycle is reached.
 3. The warning assembly as claimed in claim 1, whereina heating pipe is extendedly attached on the bottom surface of the innerpot peripherally.
 4. The warning assembly as claimed in claim 1, whereinthe predetermined times is 15 times.
 5. The warning assembly as claimedin claim 1, wherein the temperature change is ranged from the roomtemperature to 110±50° C.
 6. The warning assembly as claimed in claim 1,wherein the thermal switch is mounted on the inner pot.
